17 Claims. (Cl. 254-464) My invention relates to a cable winch of thetype wherein a cable is wound on a spool by means of a lever and is usedfor pulling loads onto trucks, pulling trees, or anything of a similarnature wherein a considerable mechanical advantage is needed in liftingor moving heavy loads.

One end of the winch is generally anchored to a fixed support, such as atree or a post and a wire cable or rope wound upon the spool is payedout and connected to the load to be moved. The cable is then rewound onthe drum by oscillating a handle which rotates a drum to rewind thecable thereon.

While cable winches of this general type are quite old, my presentdevice has several novel features which result in a more efiicient,compact and simple winch which may be easily transported from place toplace and used wherever it is necessary to apply a mechanical advantageto lift or move a heavy load.

The object of the invention is to improve the construction as well asthe means and mode of operation of cable winches, whereby they may notonly be economically and easily manufactured, but will be more efiicientand satisfactory in use, adaptable to a wide variety of applications,have relatively few parts and be unlikely to get out of repair.

It is a further object of the invention to provide a cable winch whereinthe oscillation of the handle rotates the spool by means of a pawlengaging ratchet teeth on the side or end of the spool itself so thatthe ratchet teeth are to a great extent enclosed and protected from dirtor gravel which would tend to force the pawl out of engagement with theteeth or bind the same.

It is a further object of the invention to provide a cable winch whereinthe winding spool may be freed or released from the actuating handle bymerely moving the actuating handle to an extreme position.

It is a further object of the invention to provide safety means forpreventing the accidental movement of the handle to this extremeposition and thus freeing or releasing the spool.

A further object of the invention is to provide a pawl which uponengagement with the ratchet teeth is backed up by a strong abutment soas to remove the load on the pawl from the pawl pintle and transfer itthrough the pawl to the abutment thus strengthening the winch at what isusually the weakest portion, that is, the pintle upon which the ratchetengaging pawl is mounted.

Another object of the invention is to provide a foot brake in connectionwith the cable spool which is positive in its action and may be lockedat any predetermined position either when the actuating lever is inoperative position or when the spool has been released from theactuating mechanism by moving the actuating mechanism to an extremeposition.

A further object of the invention is to provide a cable winch having allthe advantages set forth above which is relatively light in weight,yetvery strong in construction and while being easily portable, providesa definite mechanical advantage and is positive and smooth in itsaction.

A further object of the invention is to provide a cable winch having theadvantageous structural features, the inherent meritoriouscharacteristics and the mode of operation herein mentioned.

With the above primary and other incidental objects in view as will morefully appear in the specification, the invention intended to beprotected by Letters Patent consists of the features of construction,the parts and combinations thereof, and the mode of operation, ashereinafter described or illustrated in the accompanying drawings, ortheir equivalents.

Like parts are indicated by similar characters of reference throughoutthe several views.

Briefly, in the practice of my invention there is provided a cablewinding spool journaled in a frame. Embracing the spool sides is ahandle carrying yoke which is oscillatable around the periphery of thespool. An annular series of ratchet teeth are mounted in each of thesides of the spool and pawls which are resiliently urged into engagementwith the ratchet teeth are mounted on the yoke so that the yoke isoscillated in one direction, the spool will be rotated and the cablewound thereon, while oscillation in the opposite direction will resultin the pawls overriding the ratchet teeth. I also provide a set of pawlsin the frame in engagement with the ratchet teeth for preventingretrograde movement of the spool during the time the yoke is oscillatedin its free or non-winding direction.

In order to release the spool for free rotation in either direction,means are provided on the yoke and the frame which upon engagement by anextreme movement of the yoke forces both sets of pawls out of engagementwith the ratchet teeth. In order to prevent accidental extreme movementof the yoke and the disengagement of the pawls, a movable abutment isprovided on the yoke which in one position contacts the frame andprevents the engagement of the pawl releasing means, but upon anotherposition permits their engagement.

On each side of the spool and within the annular series of ratchetteeth, a brake drum is provided which encloses a pair of brake shoespivoted to the frame. A cam is provided for actuating the brake shoesinto engagement with the brake drum upon rotating an internal shaft.This shaft is rotated and the brake operated by depressing a foot leveror brake pedal which has a pawl riding on a serrated plate or rack so asto hold the brake pedal and brake in the position to which it is forced.A separate pedal incorporated in the brake pedal is also provided torelease the pawl and rack and permit disengagement of the brake.

The pawls mounted on the yoke for operating the spool as well as thepawls for preventing retrograde move ment of the spool are elongated andpintled substantially midway their ends. One end includes a spring urgedtooth engaging portion, while the other end has a cam surface. Anabutment is provided behind the cam surface of the pawls and in such aposition that when the pawls are in tooth engaging position, thecamsurface of the tail contacts the abutment, thus taking the load borne bythe pawls off the pintle and on to the abutment.

Referring to the drawings, I provide a framework having the sideportions 1 and joined together at one end by a member 2 and at the otherend by a member 3. The frame has a base portion of feet 4 whichpreferably carries slots 5 so the frame may be bolted or screwed to asurface. A hook 6 is pivotally secured on the end member 2 so the framemay be chained or fastened to a post or tree, if desired.

An idling roller 7 is mounted in the end piece 3 on a shaft 7' whichties that end of the side members 1 together. The cable to which theload is attached passes under this guide roller 7 and is secured to thecable winding spool 8 which is rotatably journaled in the side members 1of the frame.

For the purpose of rotating the spool 8 so as to wind the cable thereon,a yoke 9 is provided having a handle socket 10. The yoke 9 has twodownwardly projecting arms 11 which embrace, but are slightly spacedfrom, the spool sides or ends 12. The ends of the arms 11 terminate inbands 11 which are journaled upon brake drums 26 carried by the sides ofthe spool for concentric rotation about the shaft carrying the spool 8.Thus the yoke 9 may be oscillated about the periphery of the spool 8, asmay be seen in Figures 2 and 6.

On each of the sides 12 of the spool 8 is an annular series of ratchetteeth 13 and located on the inner side of the arms 11 of the yoke 9 arepawls generally shown at 14. The pawls 14 have a tooth engaglng portion15 which is spring urged tinto contact with the ratchet teeth 13. Fromthe above, it is apparent that upon clockwise oscillation of the yoke 9the pawls 14 will rotate the winding spool 8 in a clockwise direction inreference to Figs. 1 and 2, while a counterclockwise movement oroscillation of the yoke 9 will permit the pawls 14 to override the teeth13.

In order to prevent retrograde movement of the spool 8 at any timepawls, generally shown at 16, are mounted on the frame 1 so as to engagethe teeth 13 and prevent counterclockwise movement of the spool 8.

From the above it is apparent that the winch is driven by to and frooscillation of a handle carried by the socket in the yoke 9. Uponmovement of the handle to the right or clockwise, the spool 8 is rotatedclockwise, winding the cable in and upon the spool. In this motion thepawls 14 are in engagement with the teeth 13, while the pawls 16 mountedon the frame 1 override the teeth 13. When the handle and yoke 9 ismoved to the left, the spool 8 is prevented from reverse rotation by thepawls 16 and the pawls 14 override the teeth 13.

The pawls 14 and 16 are of a special construction, as may be seen inFig. 3. They are formed of an elongated piece of material with a toothengaging portion and 16' at one end. They are mounted on pintles 17substantially midway their length so that a tail piece 18 issubstantially diametrically opposite the tooth engaging portion 15. Anabutment 19 is positioned behind the tail piece 18 of the pawl and theterminal of the tail piece 18 carries a cam surface so that when thetooth engaging portion of the pawl is in tooth engaging position, thecam surface of the tail piece 18 is in contact with the abutment 19. Onthe other hand, the cam surface is so shaped that when the pawl is outof tooth engaging position or in its retracted position, the cam surfaceof the tail piece 18 is free of the abutment 19.

From the above it is apparent that when the pawls 14 and 16 are engaginga tooth, the load borne by the pawls is transferred from the pintle 17to the abutment 19. This construction permits the use of relativelylight pintles 17, since the load is not borne by the pintle when thepawl is in engagement with the tooth and bearing a load.

In order to release the spool from engagement with the yoke 9 or theframe 1 and permit its free rotation in either direction, means isprovided on the yoke and the frame which contact and cooperate with eachother when the yoke 9 is moved to its extreme clockwise position. Thismeans consists of rods 20 and 21 slidably journaled in sleeves which arepreferably a portion of the abutment 19 (see Fig. 3). These rods 20 and21 are positioned in their journals with a cam surface in alignment witha portion of the cam surface on the tail end 18 of the pawls 14 and 16.In the case of the rod 20, the end 20' is beveled and in the case of therod 21 a portion 21 is cut out so as to accommodate the tail 18. Thereis a projecting end 22 on each of the rods 20 and 21 and theseprojections are in circumferential alignment so that when the yoke 9 ismoved to its extreme clockwise position, the two rod ends 22 willcontact and both rod 20 and rod 21 will be forced into its journal andthe cam followers 20' and 21' will act upon the cam surface or the tails18 of the pawls and retract the same (see Figs. 2 and 3). Rods 20 and 21are normally maintained in the position shown in Fig. 3 by means of thespring biased pawls 14 and 16 so that when the ends 22 are out ofcontact, both pawls 14 and 16 are spring urged to tooth engagingposition which they resiliently maintain at all times, unless the rods20 and 21 are retracted.

Referring to Fig. 2, it should be noted that the yoke 9 is shown almostin its extreme right clockwise position and the ends 22 of the rods 20and 21 are just in contact. Upon further movement of the yoke 9 to theright, these rods 20 and 21 would be forced inwardly and the pawls 14and 16 would be retracted from tooth engaging position.

Referring to Fig. 2, the circumferential alignment of the pin ends 22will be noted.

In order to prevent the accidental movement of the yoke 9 to its extremeright position and the withdrawal of pawls 14 and 16 from tooth engagingposition, a safety guard is utilized which is best shown in Figs. 5 and6 and which consists of a wire bale 23. This wire 23 is mounted on theyoke 9 by means of a bracket 24 at each end of the yoke 9. The ends ofthe wire which project beyond the bracket 24 are bent in the form of anabutment or loop 25. By turning the wire 23 in the brackets 24, theloops 25 may be made to project outwardly from the yoke 9 as shown inFig. 6. In this position they form an abutment which will contact theframe 1 when the yoke 9 is moved to the right before the rod ends 22 aredepressed, thus preventing the extreme clockwise movement of the yoke 9which would actuate the rods 20 and 21 and release the pawls 14 and 16.However, when the loops 25 are moved downwardly or to the position shownin Fig. 5, they are out of the way and no longer form an abutment andpermit the yoke 9 to be moved to its extreme position, thus resulting inthe withdrawal of the pawls 14 and 15 from tooth engaging position.

In order to provide a control over the spool 8 when the pawls 14 and 16are retracted and the spool is free running, a manually controlled brakeis incorporated. The brake consists of a brake drum 26 fastened to eachside 12 of the spool 8 (see Figs. 1 and 6). Within the brake drum 26 area pair of brake shoes 27 which are pivoted at 28 in the usual manner tothe frame 1. A shaft 29 runs through the core of the spool 8 and carriesa brake actuating cam 30 within the brake assemblies, as shown in Fig.6. This brake is of a well-known type and it is apparent that when theshaft 29 is rotated clockwise in Fig. 6, the brake elements 27 will moveoutwardly and apply the shoe itself to the interior of the brake drum 26and slow down or stop rotation of the spool 8 in either direction.

Keyed to the ends of shaft 29 and outside of the frame 1 is a foottreadle 31 and a hand lever 31' for rotating the shaft 29 as describedabove. Preferably the foot treadle 31 has a pawl arm 32 which rides overa rack 33 and locks the brake pedal 31 in the position to which it ismoved. To release the braking mechanism and the foot treadle 31, arelease link 34 is incorporated (see Fig. 2), which upon actuationremoves the pawl 32 from the rack 33 and permits the treadle 31 toreturn to its normal brake released position, the treadle 31 beingspring urged to its non-braking position.

From the above it is apparent that the operator has complete controlover the rotation of the spool 8 in either direction by means of thefoot treadle 31 or hand lever 31' and the brake latching pawl 32, eventhough the pawls 14 and 16 are disengaged from the ratchet teeth 13. Insome cases where it is desirable, the braking mechanism may also be usedwith the pawls 14 and 16 in tooth engaging position.

As a modification a split or double spool 35 and 36 may be mounted on acommon shaft, but disconnected from each other. so as to freely rotateindependently in either direction. The annular series of ratchet teethon one of the spools, as an example 35, is in one direction as in 37,while the ratchet teeth on the side of the other spool 36 is reversed asin 38. In this case, the pawls 14 which are mounted on the arms 11 ofthe yoke 9 are positioned to engage and actuate the ratchet teeth 37 and38. In other words, one pawl is reversed in reference to the other. Bythis construction, as the yoke is oscillated right and left, spool 35 isrotated in one direction, while spool 36 is the reverse direction.

In this case, the pawls 16 which prevent retrograde movement are alsopositioned so as to accommodate the teeth which they are designed toengage, i. e., one is reversed in reference to the other.

By the above modified construction, balanced or measured oscillation ofthe handle moving the yoke 9 will take in cable from opposite directionsuniformly. In this modification with the split spool, it may bedesirable to provide a second guide roller similar to 7 on the oppositeside of the winch and to form the rear end 2 similar to the front end 3.

From the above it is apparent that there is provided a cable winch whichis extremely simple and rugged in construction but wherein a greatmechanical advantage is gained in its operation, as well as flexibilityin its control. The ratchet teeth are on the sides or faces of the spoolends instead of the periphery, thus preventing the accumulation of dirtin the pawls and teeth and the very real danger of catching materialsuch as clothing in the teeth during operation of the winch.

The spool of the winch is easily and quickly freed for rotation ineither direction by merely moving the operating handle to a terminalposition and when this is done the movement of the spool may becarefully and positively controlled by the brake, which in turn isactuated by a foot treadle. The foot treadle may be depressed justsufliciently to slow down the rotation of the spool and held in thatposition, or it may be brought fully down and the rotation of the spoolstopped.

Such winch is relatively inexpensive to manufacture and any repairs,when necessary, are extremely simple. The winch is a complete unit andmay be transported from place to place without difliculty. It may befastened to a tree or a post or bolted or screwed to a flat surface or atruck bed, if desired.

From the above description it will be apparent that there is thusprovided a device of the character described possessing the particularfeatures of advantage before enumerated as desirable, but whichobviously is susceptible of modification in its form, proportions,detail construction and arrangement of parts without departing from theprinciple involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has beendescribed in language more or less specific as to structural features,it is to be understood that the invention is not limited to the specificfeatures shown, but that the means and construction herein disclosedcomprise but one of several modes of putting the invention into effect.
